A class of effect size indices are discussed that evaluate the degree to which two nested confirmatory factor analysis models differ from each other in terms of fit to a set of observed variables. These descriptive effect measures can be used to quantify the impact of parameter restrictions imposed in an initially considered model and are free…

The number of studies providing empirical evidence on e-learning in the field of special education is limited. From this point of view, the aim of this study is to examine whether the factors influencing the e-learning adoption of university students with disability differ according to the type of disability and gender. The participants of the…

The current research investigated the psychometric characteristics of the Turkish adaptation of the Teacher Emotions Scale (TES). Study I included a sample of 164 Turkish middle school teachers, and Study II included a sample of 222 mathematics teachers. The three-emotion factor model was confirmed in both studies with satisfactory reliability…

The purpose of this study is to develop a valid and reliable scale to determine the life and career skills of university students. 396 university students in Turkey who look for work have participated in Exploratory Factor Analysis (EFA) and also data were collected from 439 students for Confirmatory Factor Analysis (CFA). According to the result…

The present study aims to develop a valid and reliable pedagogical literacy scale based on teachers' views. It also aims to investigate the variations in pedagogical literacy levels of teachers based on gender, educational level, and professional seniority variables to test the functionality of the pedagogical literacy scale. The study was…

The purpose of this research is to develop a valid and reliable "Innovative School Leadership Scale" and examine the innovation level of school principals. Within the scope of the research, an "Innovative School Leadership Scale" with 28 items was developed. In the trial application, 197 teachers were reached, and 523 teachers…

Introduction: The COVID-19 pandemic has generated repercussions in higher education. Therefore, the objective was to determine whether the use of virtual academic media, academic repercussions and adaptability predict satisfaction with studies in university students. Method: Explanatory and transversal study, in which 725 university students of…

The teaching profession in the researcher's context is becoming a machine-like job because teachers' followership i.e. competence, commitment, courage, and self-management, is least prioritized, and more focus is given only on their regularity and punctuality. Effective followership is desired among the teachers for the achievement of educational…

Recent advancements in testing differential item functioning (DIF) have greatly relaxed restrictions made by the conventional multiple group item response theory (IRT) model with respect to the number of grouping variables and the assumption of predefined DIF-free anchor items. The application of the L[subscript 1] penalty in DIF detection has…

Background: Children with reading difficulty exhibit deficits in multiple cognitive areas (e.g., language skills, working memory, processing speed). Therefore, evaluation of reading difficulty typically includes assessment of both academic functioning and general intelligence (IQ). Although the IQ construct is considered robust in the general…

The purpose of this study is to evaluate the performance of three commonly used model fit indices when measurement invariance is tested in the context of multiple-group CFA analysis with categorical-ordered data. As applied researchers are increasingly aware of the importance of testing measurement invariance, as well as Likert-type scales are…

The aim of the study is to investigate the measurement invariance of mathematics self-concept and self-efficacy across 40 countries that participated in the Programme for International Student Assessment (PISA) 2003 and 2012 cycles. The sample of the study consists of 271,760 students in PISA 2003 and 333,804 students in PISA 2012. Firstly, the…

Fluency confound (FC) has been a widely studied issue in divergent thinking (DT) tasks. In this study, the impact of DT task structure on FC was examined by focusing on activity level data from Torrance Tests of Creative Thinking (TTCT)-Figural. The TTCT-Figural involves two different task structures. Prompts in Activities 1 and 2 are designed for…

Through the design of a survey and measure validation using exploratory factor analysis (EFA), we aimed to identify and define constructs required for special education teacher leadership that may inform the focus of professional development opportunities. Results of the analysis indicate a four-factor model is best suited for measuring special…

It has been debated whether working memory (WM) performance is modulated by the valence of the stimuli that are being processed. A recent meta-analysis revealed that at the behavioral level and in individuals without mental health problems, mean-level performance differences in WM tasks with neutral versus affective conditions are small to…
